PVAm-Grafted N, S-Co-Doped Carbon Dots: A Robust Fluorescent Probe for Selective Detection of Ferric Ions

Key Points

• The robust fluorescent probe effectively detects ferric ions with high selectivity.
• Using this method, the detection limit for ferric ions was measured at 0.5 µM.
• The analysis involves synthesizing N, S-co-doped carbon dots modified with polyvinylamine.
• This approach highlights the potential for developing optical sensors in environmental monitoring.
